Marinate the Steak: Whisk together olive oil, minced garlic, lemon juice, dried oregano, thyme, salt, and black pepper in a bowl. Add the sirloin steak and ensure it’s coated. Cover and marinate for at least 30 minutes or up to 4 hours.

Prepare Tzatziki Sauce: In a separate bowl, combine Greek yogurt, chopped dill, minced garlic, lemon juice, and salt. Stir until creamy and refrigerate for at least 15 minutes.

Make Vinaigrette: Whisk together olive oil, honey (if using), lemon juice, salt, and pepper in a bowl, adjusting to taste. Set aside.

Cook the Steak: Heat a skillet over medium-high heat, sear the marinated steak for 4-5 minutes each side until medium-rare. Let it rest for 5 minutes before slicing thinly.

Assemble the Bowl: Start with a base of cooked grains, layer sliced steak, add toppings, and drizzle with tzatziki and vinaigrette.
